A type of bdsm play were one partner is tied up and deprived of normal senses
Eg. Blindfolded, ear plugs, gagged
They are left for a period of time for their senses to get used to it then the other partner comes back at any unknown time, light touches will give extra pleasure. Even if not in a particularly sexual area. Causes more intense orgasms and pleasure
My boyfriend and I tried spider walking last night and holy crap
